How to transform this array?

Question

I have a form that in certain fields returns me several possibilities of data in a single index when I print the array. This situation can be seen in índices 3, 4, 5 e 7.

Array
(
    [0] => APARTAMENTO
    [1] => CASA
    [2] => CASA EM CONDOMINIO
    [3] => COBERTURA/COBERTURA HORIZONTAL
    [4] => CONJUNTO/SALA/LOJA
    [5] => FLAT/LOFT
    [6] => PREDIO COMERCIAL
    [7] => TERRENO/AREAS
)

I need to get to this result in PHP so that then I can start my queries in the database:

Array
(
    [0] => APARTAMENTO
    [1] => CASA
    [2] => CASA EM CONDOMINIO
    [3] => COBERTURA
    [4] => COBERTURA HORIZONTAL
    [5] => CONJUNTO
    [6] => SALA
    [7] => LOJA
    [8] => FLAT
    [9] => LOFT
    [10] => PREDIO COMERCIAL
    [11] => TERRENO
    [12] => AREAS
)

I arrived at this result with this form:

<input type="checkbox" name="tipo[]" value="APARTAMENTO" id="tp1">
<label for="tp1">Apartamento</label>

<input type="checkbox" name="tipo[]" value="CASA" id="tp2">
<label for="tp2">Casa</label>

<input type="checkbox" name="tipo[]" value="CASA EM CONDOMINIO" id="tp3">
<label for="tp3">Casa Condomínio</label>

<input type="checkbox" name="tipo[]" value="COBERTURA/COBERTURA HORIZONTAL" id="tp4">
<label for="tp4">Cobertura</label>

<input type="checkbox" name="tipo[]" value="CONJUNTO/SALA/LOJA" id="tp5">
<label for="tp5">Conjunto/Sala/Loja</label>

<input type="checkbox" name="tipo[]" value="FLAT/LOFT" id="tp6">
<label for="tp6">Flat/Loft</label>

<input type="checkbox" name="tipo[]" value="PREDIO COMERCIAL" id="tp7">
<label for="tp7">Prédio Comercial</label>

<input type="checkbox" name="tipo[]" value="TERRENO/AREAS" id="tp8">
<label for="tp8">Terreno/Área</label>

Passing only that as instruction:

$tipo = $_GET['tipo'];

For layout reasons, I cannot make these fields different, like um tipo por input. Any idea??

Answer 1

A simple way would be using implode in the array using '/' and then turning into array with explode '/'. I just played in the ideone.

$array = array(
0 => 'APARTAMENTO',
1 => 'CASA',
2 => 'CASA EM CONDOMINIO',
3 => 'COBERTURA/COBERTURA HORIZONTAL',
4 => 'CONJUNTO/SALA/LOJA',
5 => 'FLAT/LOFT',
6 => 'PREDIO COMERCIAL',
7 => 'TERRENO/AREAS',
);

print_r( explode( '/' , implode( '/' , $array ) ) );
// output abaixo
Array
(
    [0] => APARTAMENTO
    [1] => CASA
    [2] => CASA EM CONDOMINIO
    [3] => COBERTURA
    [4] => COBERTURA HORIZONTAL
    [5] => CONJUNTO
    [6] => SALA
    [7] => LOJA
    [8] => FLAT
    [9] => LOFT
    [10] => PREDIO COMERCIAL
    [11] => TERRENO
    [12] => AREAS
)
